# Expert Advice:

01 -
  • Its essentially a deconstructed fajita but easier and faster than wrapping individual tortillas
  • The melted cheese creates this incredible golden crust that everyone fights over
02 -
  • I once forgot to drain the diced tomatoes and ended up with fajita soup instead of casserole
  • The cream cheese needs to be truly softened or you will end up with lumpy pockets instead of a creamy sauce
03 -
  • Cook your vegetables until they are actually soft, not just heated through, because they will not soften much more in the oven
  • Use the large side of a box grater to shred your cheese for faster melting
